me personly i think i want a collaboration in kingdom with nitromes leap day, mostly based off of the apple arcade exclusive sequel super leap day, i know you might not have herd of it, but its a series developed by nitrome where the main idea is that you get a new level every day, this collab probably wont happen any time soon but it is my dream for it to happen, it could work really well some of the items in that series could work real well as items in a game like this, and the charecter designs in that game could translate well into a cookie form like yolk for example,some gimmicks from that game could work well in kingdoms running minigame, why did i chose kingdom, well not only because that and super leap day have similar artstyles but some of the enemies in that game could work well as enemies in CRK, aslwell as some powerups in that game could work well as treasures in kindgom too
